Google cloud outage caused by failure that saw admins run it manually ... and fail

A mistaken peering advertisement from a European network took #GoogleCloud 's europe-west1 region offline last week for around 70 minutes.

The slip-up happened when an unnamed network owner connected a new peering link to Google, and in the process, it advertised reachability for far more traffic than it could handle.

As a result, as The Chocolate Factory explains in this post, most of the lost traffic carried destination addresses in eastern Europe and the Middle East.

“The peer's network signalled that it could route traffic to many more destinations than Google engineers had anticipated, and more than the link had capacity for. Google's network responded accordingly by routing a large volume of traffic to the link. At 11:55, the link saturated and began dropping the majority of its traffic”, the post states.
